I gave the device five stars for its usefulness, but I'd rate the instructions (and packaging) two stars. It's very hard to get these batteries out of their very tight packaging! I was afraid I was going to break it. And the instructions are very vague. Sure, I could figure out what to do, but I had questions that weren't answered (and could/should have been either in the instructions or on outside of the box).
1) "Is the battery already charged?"
2) "How do I know if it is?"
3) "How many charges does it hold?"
4) "How do I know when it's fully charged?"
5) "How long does it take to charge my iPhone?"
These are questions I had to figure out myself. To answer them:
1) Yes, the battery is charged, but it only had two charges at the start when I took it out of the package.Read more ›
This battery has a 8800 mAh charge capacity, which in theory should give me 6x charging of an iPhone 4S (1449 mAh) or iPhone 5 (1440 mAh). In my testing, I am able to charge two iPhones fully, and then charge another iPhone to almost-full. So I am only able to get half as much as what I should get out of this battery. I am still pleased by this portable backup battery, but the performance is a bit lacking.
When charging two devices at once, note that the maximum power output of the battery is 2.1A (not 2.1A per port). If you want to charge both a tablet and a phone at the same time, you may choose how to split the power between the dual ports:
-If you want to split it evenly, connect the phone first, press the power button, and then connect the tablet.
-If you want to provide full power (up to 2.1A) to a tablet, connect it first and press the power button.
There are four LEDs beside the copper power button. A short press will cause the LEDs to illuminate briefly to indicate the power level.
Off to other things about this battery...
What I like:
-Can charge two phones simultaneously (or a phone and tablet... at least on paper); note that charging two devices at the same time will take longer to charge (max output is 2.1A total, not 2.1A per port)
-Larger capacity than many other backup batteries I've used
-Can be charged on a ...Read more ›
The device DOES work. It is, however, incredibly SLOOOOOWWWWW. My Kindle Fire took from 7am until dinner time to charge. My roughly half-empty iphone 5 took about 4-5 hours.
And the device itself can only be charged via a USB cable. There's not AC adapter. And that took a long time...I actually charged it over a couple of days. I'd guess nearly 10 hours for a charge.
I don't know how long it takes to drain it all the way...but after I charged my Kindle Fire, it took about 5 hours to get it back to full. No idea how drained it was.
So technically, this device does work, and I imagine I'll use it some when travelling. But it is by NO MEANS a miracle worker. Set expectations accordingly, and REALLY think about whether it's worth the $ to you. As you see, I was fortunate enough to receive this from the Vine program in exchange for my thoughts. I would NOT have been happy if I had paid $120 or so for it. It might be worth it for you if you're a road warrior or a camper or something like that. But again, really think about what I've described if it is worth the price.
